SwitchRes is a little utility, built around a menu extra that will allow you to switch the resolution of all your monitors. SwitchRes already incorporates features from the Monitor Resolution, Monitor BitDepth, and Video Mirroring Control Strip Modules bundled with your system.

My Samsung 37&quot; B530 wouldnt work at the best resolution if wasnt SwitchResX. I could easily change the hertz related to the external monitor to 59 instead of 60, and it worked perfectly!!! This prefpane totally worth the price.
